2014-03-31ethtool: Centralise validation of ETHTOOL_{G, S}RXFHINDIR parametersBen Hutchings
Add a new ethtool operation (get_rxfh_indir_size) to get the indirectional table size. Use this to validate the user buffer size before calling get_rxfh_indir or set_rxfh_indir. Use get_rxnfc to get the number of RX rings, and validate the contents of the new indirection table before calling set_rxfh_indir. Remove this validation from drivers.

2011-06-27vmxnet3: Convert to new vlan model.Jesse Gross
This converts the vmxnet3 driver to use the new vlan model. In doing so it fixes missing tags in tcpdump and failure to do checksum offload when tx vlan offload is disabled.

Convert vmxnet3 driver to 64 bit statistics interface. This driver was already counting packet per queue in a 64 bit value so not a huge change. Eliminate unused old net_device_stats structure.

2011-05-16vmxnet3: Fix inconsistent LRO state after initializationThomas Jarosch
During initialization of vmxnet3, the state of LRO gets out of sync with netdev->features. This leads to very poor TCP performance in a IP forwarding setup and is hitting many VMware users. Simplified call sequence: 1. vmxnet3_declare_features() initializes "adapter->lro" to true. 2. The kernel automatically disables LRO if IP forwarding is enabled, so vmxnet3_set_flags() gets called. This also updates netdev->features. 3. Now vmxnet3_setup_driver_shared() is called. "adapter->lro" is still set to true and LRO gets enabled again, even though netdev->features shows it's disabled. Fix it by updating "adapter->lro", too. The private vmxnet3 adapter flags are scheduled for removal in net-next, see commit a0d2730c9571aeba793cb5d3009094ee1d8fda35 "net: vmxnet3: convert to hw_features". Patch applies to 2.6.37 / 2.6.38 and 2.6.39-rc6. Please CC: comments.

2011-04-29ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny
This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation. All drivers compiled with make allyesconfig ion x86_64 have been updated. Tested: make allyesconfig on x86_64 + e1000e/bnx2x work Signed-off-by: David Decotigny <decot@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-03-27net: fix ethtool->set_flags not intended -EINVAL return valueStanislaw Gruszka
After commit d5dbda23804156ae6f35025ade5307a49d1db6d7 "ethtool: Add support for vlan accleration.", drivers that have NETIF_F_HW_VLAN_TX, and/or NETIF_F_HW_VLAN_RX feature, but do not allow enable/disable vlan acceleration via ethtool set_flags, always return -EINVAL from that function. Fix by returning -EINVAL only if requested features do not match current settings and can not be changed by driver. Change any driver that define ethtool->set_flags to use ethtool_invalid_flags() to avoid similar problems in the future (also on drivers that do not have the problem). Tested with modified (to reproduce this bug) myri10ge driver. Cc: stable@kernel.org # 2.6.37+ Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: David S.

2009-11-17net: Getting rid of the x86 dependency to built vmxnet3Shreyas Bhatewara
This patch removes config dependency on x86 to build vmxnet3 driver. Thus the driver can be built on big endian architectures now. Although vmxnet3 is not supported on VMs other than x86 architecture, all this code goes in to ensure correctness. If the code is not dependent on x86, it should not assume little endian architecture in any of its operations. Signed-off-by: Shreyas Bhatewara <sbhatewara@vmware.com> Signed-off-by: David S.
